Hi,
Im currently working on an issue im having with a ruby method within my
rails project.
i have this method:
def saveAssetTags(asset, taglist)
#add new tags
tagList = taglist.split(/\s*\,\s*/)
#drop all current tags
asset.tags.clear
for metadata in tagList
tag = Tag.find_by_Tag(metadata)
unless tag
tag = Tag.new
tag.Tag = metadata
tag.save
end
asset.tags << tag
end
end
its taking in a list of tags from the client seperated by comma's and
putting them into an array before saving them in my database. this all
works fine unless a user enters the same tag twice in which case i get a
duplication error in the db.
whats the best way to check the array for repeating attributes or to
check as i iterate through the loop?
Cheers,
Chris
